Hi dongggoi,

If you've used GEM in the past, I'm surprised that the GEM Genesys hasn't been mentioned, I know it's discontinued but maybe it can be picked up at a good price now? I think there's a 76 and 61 model.

As for me, I own a T3 and I am more than happy with it, estatic actually, it was either this or the Audya those were the only two that caught my eye from owning the Korg PA1x for 5 years. Still have the PA1x though and it isn't going anywhere, it's a beautiful machine and I think it will be a rare model as it uses high quality components and great sound system for a 61 key model.

Good Luck,
Danny.
